Apple flogged 3 million of its newest iPads -- the iPad with retina display and its Mini-Me, the iPad mini -- last weekend. The Californian company boasts this is a record for its tablets, doubling the 1.5 million Wi-Fi only iPad 3s it shifted after its first three days on sale in March.

It's hard to compare like for like here, but all these numbers give us some idea of relative popularity. Apple hasn't said how many iPad minis it sold compared to retina iPads, possibly because it doesn't want stories about cannibalising its own sales. It does, however, give genuine sales figures, whereas Samsung and Asus tend to put out numbers for units shipped -- ie how many tablets or phones have left the factory and reached shop shelves, as opposed to being bought by punters.

Meanwhile, an analysis of the materials used in the iPad mini by teardown specialists IHS iSupply claims the £269 16GB iPad mini costs $188 (£118) for the parts and $10 (£4.40) for 'manufacturing expense'. There's no way of knowing if that's accurate -- Apple's contracts with its suppliers are top-secret, so it could well be getting a much better deal on those parts, particularly as it's buying millions of them.

The price doesn't take into account how much it costs to design a new product, or develop and maintain its software -- costs the iPad mini will share with its iPad and iPhone brethren. Nevertheless, if that educated guess is accurate, it shows just what bargains the £159 Google Nexus 7 and Amazon Kindle Fire HD are, thanks to generous subsidies from their makers, who are desperate to add you as a paying customer for their apps and services.
